Pupil dilation reflects interference during memory retrieval
We demonstrate that pupillometry can be used to track memory interference independent of explicit responses. Pupil diameter was recordedthroughout encoding and retrieval of words from the same category over 4 trials, causing buildup of proactive interference (PI). In a contrastingcondition, the category was switched on the 4th trial, causing release from interference (RI). Pupil dilation systemati
